Procedure
Methyl hydroxyacetate (22 mg, 0.24 mmol) and 2-(5-(3-[(4-chloropyrimidin-2-yl)amino]-5-methylphenyl)-1,3-thiazol-2-yl)-1,1,1-trifluoropropan-2-ol (Example 98, 50 mg, 0.12 mmol) were taken up in N,N′-dimethylacetamide (1.2 mL). Cesium carbonate (118 mg, 0.36 mmol) was added and the mixture was stirred for 24 h at 70° C. The reaction was cooled to room temperature, quenched with saturated aqueous ammonium chloride, and extracted with ethyl acetate (2×). The combined organics were concentrated under reduced pressure and purified by reverse phase HPLC (10-80% acetonitrile/water+0.05% TFA modifier). Desired fractions were combined and lyophilized to afford {[2-({3-methyl-5-[2-(1,1,1-trifluoro-2-hydroxypropan-2-yl)-1,3-thiazol-5-yl]phenyl}amino)pyrimidin-4-yl]oxy}acetic acid (10 mg, 0.018 mmol, 15%) as the trifluoroacetic acid salt as a white solid. MS ESI: [M+H]+ m/z 455.1.
